Embodiment 1

[0042] A kind of PP composite material with the function of releasing negative ions, the composition is as follows by weight percentage:

[0043]

[0044] (1) Add the copolymerized PP, coupling agent, and toughening agent in proportion to the high-speed mixer and mix for 3-5min at a speed of 50-80r / min;

[0045] (2) Mix self-made negative ion powder, talcum powder, and odor absorbing agent at a speed of 80-100r / min for 2-4min so that each component can be fully mixed evenly;

[0046] (3) Add the remaining weather-resistant and anti-aging additives, lubricants, super-active nano-calcium, scratch-resistant additives, and self-made hollow glass microspheres into the mixer and mix for 1-2 minutes;

[0047] (4) Extrude the mixed raw materials in a twin-screw extruder with a length-to-diameter ratio of 40:1. The processing temperature of the extruder is set to ten temperature zones, and the temperature of each temperature zone is 180°C, 190°C, 200°C, 210°C, 210°C, 210°C, 210°C, ...
